How to plot time series at a fixed point for SPH simulation (.vtu) in ParaView

Hi,

I’m visualizing an SPH simulation in ParaView using .vtu files with multiple time steps.
I would like to plot the time evolution of a variable ( like pressure or Z-variation because it’s a fluid simulation) at a fixed spatial point.

I tried using Probe Location and Plot Data Over Time, but I only get constant or zero values.

What is the best way to extract interpolated time series data at a given point in SPH simulations?

thank you in advance .

Please share your data.

i shared the .pvd files ( i think they are the same as the .vtu files )

You need to share the .vtu files too.
